with him since then, and we look forward to his help this year.
In the Publications Review, we
emphasized the turnaround in the
quality of our Transactions since our
last review five years ago, when we
were criticized for inadequate peer
review. Since then, we've grown from
three Associate Editors to a current
roster of twenty, augmented by IEEE
Publications Office staff. More than
150 others volunteered their time and
expertise to our peer review process
last year. As of this writing, we've yet
to receive the official comments back

From the Editor continued
on Broadcasting which is celebrating
its 50th anniversary this year. Thanks
to the Queens Borough (New York)
Public Library and our society administrator April Nakamura we have
located a copy of that first issue. The
library was kind enough to fax April
the first several pages and we are
reprinting the table of contents and
the title page to give you an idea
what hot topics of the day were in
March 1955 and who was leading the
organization. From that issue it is
noted that the vice-chairman of the
administrative committee was Scott
Helt in whose honor we present the
annual award for the best transactions -paper.
I also note that the papers in that
first issue were all presented at the
4th Annual Broadcast Symposium
held in Cleveland, OH in September
of 1954. We are now preparing for the
55th Annual Symposium and paper
abstracts are due by May 25, 2005
(see the call for papers in this issue
for details).
Congratulations are also in order
for Ed Williams on his retirement from
PBS but thankfully not from the BTS See more details inside.
In this issue we have once again,
thanks to Dmitry Tkachenko, a good
report from our chapter in St. Petersburg, Russia and Valentin Trainotti
has provided a report from o u r
chapter in Argentina. I know that we
have a number of active chapters
and a great way to help increase

know next time how we fared.
We're looking forward to seeing
many of you at NAB next month. Our
tutorial has moved from Saturday to
Wednesday afternoon this year, to
avoid conflicting with the SBE Ennes
Workshop. Yiyan Wu will be presenting a portion of our Symposium tutorial on "Video and Audio Distribution
via Wireless Broadband," I'll describe
the various activities of the IEEE 802
standards committees, and Victor
Tawil of MSTV will provide an update
on the FCC's proposed rulemaking
allowing unlicensed devices to operate in the TV broadcast bands. April
Nakamura and Jerry Berman will be
nearby at our membership booth.
We've also begun planning for
another joint tutorial with SMPTE at
IBC in September. Although still in the
proposal stage, we hope to present
real-world experiences in implementing HDTV, as related by an interna-
Tom at the Alamo
tional panel of experts. Stay tuned for
further details as our plans gel.
As always, we welcome your comments and ideas by e-mail or by logging onto the BTS Virtual Community.

1. Meeting Called to order 2:30 PM
2. Introductions and welcome.
a.Mr. Gurley extended a special welcome to Ralph
Wyndrum, Vice President of TAB, who has been visiting Society AdComs. He noted that Moshe Kam,
Chair of the IEEE Membership Project, also would be
joining the meeting.
3. Mr. Gurley turned the floor over to Ralph Wynclrum for
his presentation, summarized below:.
a.Mr. Wyndrum said that, as the TAB VP, it is his job to
ensure the health of the Societies and make sure they
are contributing to IEEE as best they can and bring
that philosophy to TAB. Mr. Wyndrum has visited a
number of small, medium and large Societies. Societies are the heart and soul of TAB, the source for
money and the source of technical content. They are
in various degrees of array and disarray and he has
been working with them to get them back on track.
Many of the Societies are struggling for money, and it
is affecting the Society's morale. AdComs' decisions
to cut costsaffect technical programs and volunteers.
The time has come to cut back on the tax Societies
pay to cover IEEE overhead. Mr. Wyndrum took this
message to Art Winston a n d IEEE FinCom, which
agreed to cut the 36% increase in indirect overhead
back to the rate of inflation. The Executive Committee has recommended reducing the budget, but serious cutbacks will have to occur.
b. Publications
i. Publications provide $30 Million/year for use by
the IEEE. We now face competition from the web,
open access & competitors (Reed, Elsevier). Mike
Lightner and Mr. Wyndrum are in a strategic planning committee which will be developing strategic
responses to these problems. With electronic publishing, the users are not realizing that a publication is from a specific Society.
ii. The British Government and US National. Institutes
of Health are saying that if they pay for any part of
research, the results must b e available for free.

c. Conferences
d.Conferences g e n e r a t e $10 million/year. IEEE is
attempting to identify exactly what is the impact of
conferences to our membership, volunteers, a n d
members.
i. There will be a weekend of conference strategy
with representatives from Societies, Sections, N&A
etc.
e . Distinguished Lecturer program
i. Sections and Regions have had trouble getting Distinguished Lecturers in locations where there are
small audiences and difficulties in traveling to those
locations.
ii. Mr. Wyndrum asked how close BTS feels to its
Chapters?
1. Mr. Gurley replied that, in the past few years,
we have tried outreach to our chapters including
the offer of money. Additionally, we have provided speakers for their events. We want to have
more Chapters, a n d have helped a few new
ones form, but have had a complaint that there
is some hesitation from a Section.
2. Mr. Wyndrum suggested that w e form Joint
Chapters - with COM, CE, etc. This may be a
valuable way to increase membership and to get
better opportunities to bring Distinguished Lecturers to our events.
f. Mr. Gurley asked about the status of the IEEE cost of
membership project.
i. Mr. Gurley noted that the IEEE has been raising
dues by the cost of living, and in BTS we find that
people don't join because the cost of membership
is too high, or have dropped Society memberships
because the cost of IEEE membership has gone u p
and they need to keep the price level.
ii. Mr. Wyndrum replied that IEEE's cost seems to
match that of comparable membership Societies.
iii.Moshe Kam noted that the problem may not be the
cost, but that members d o not see the value for the
Spring 2005
membership.
4. Society Overview Presentation: Tom Gurley made a
PoarerPoint presentation to overview the Society's
strategic planning, and membership issues. (See Sidebar)
5 . The AdCom next heard a presentation from IEEE Membcrship Development Committee Segment Initiative
Chair : Moshe Kam
a.The IEEE Membership Project: Volunteer and Members see us as a Membership organization not just as
conference organizers and publishers. The IEEE's success is related to t h e number of Members a n d
income. In IEEE's traditional areas of strength, our
market share is declining and we are not well organized to senre non-traditional members. Membership
revenue is very significant and there are some very
serious competitors from Academia and For-Profit
Companies. Project organized in early 2004.
b.Address areas that are "undersenred" by IEEE.
i. Healthcare, multimedia, broadcasting, entertainment, Pre-College Education, Information Tech.
ii. Determine what these groups may need from IEEE
c.The Membership Project: will change membership
level titles
6 . Review of Publications and Society Review
a.The AdCom nras asked to read and provide feedback
on many of the questions.
7 . Previous Meeting Minutes were approved, and it was
noted that all action items had been completed.
8. Awards and Nominations report:
a.Awards: All plaques and certificates are prepared to
be given out at tile li~ncheon.
b.Nominations 5: Elections:
i. R. Freidel, W. Meintel, and D. Tkachenko will run
for a second tern1 on the AdCom.
ii. Nominations for two other seats will be sought at
the Symposium, and other candidates were suggested by the AdCom.
iii. President and Vice-President elections.
1. Tom Gurley and Charles Einolf nominated by
Sid Shumate. Motion by Lanny Nass, and Second by R. Freidel. Approved Unanimously.
9. Treasurer's Report
a.The AdCom received a report from Treasurer Lanny
Nass. It appears that the Society has a net worth of
about half a million dollars.
10. Standards Report
a.W. Hayes thanked G. Best for his recent Standards
work and plans to d o work for the RF committee.
b.W. Hayes and A. Nakamura held a teleconference
with A. Ortiz of IEEE Standards Staff:
i. P206: We will reaffirm because it is still in use
ii. P???: Wre will reaffirm because it is still current
iii.P746: Appears to be current and should be reaf-
firmed
iv. 1486: TV interlace for signals which have been
compressed. This should be kept alive.
1. W. Hayes will draft a paragraph to reaffirm the
standard.
v. Tli Camera Resolution Chart - W. Hayes will look
this up and find out about it.
c. W. Hayes has reviewed all of the above standards and
will reaffirm them.
d.IEEE 802 Committee:
i. IEEE 802.18, the Radio Regulator), Technical Advisory Group, is drafting comments o n the FCC
Notice of Proposed Rulemaking on use of unlicensed devices in the T V broadcast bands.
1. The group needs more participation by broadcasters. T. Gurley has agreed to be the BTS liaison to that committee and another. 802.22,
which is a committee chartered to develop a
standard for wireless regional area networksoperating on unused 'T'V Channels.
2. The work is being driven by wireless interests
who want to build the chips and products. The
only Broadcaster participating has been FOX,
and we need to get more of them involved.
11. IBC Report
a.The IBC2004 drew approximately 41,000 attendees.
Stand sales for 2005 are ahead of budget.
b.A joint tutorial with SMPTE took place. Greater coordination and advertising should take place in 2 0 5 .
c.In order for BTS to get onto the conference program
each year. we need to get onto the conference program committee. \Xi. Hayes volunteered, and T. Gurley needs to contact IBC and get that done.
d.The BTS needs to be taken seriously at the IBC.
12. USRI Report
a.The AdCom gratefully received G. Berman's USTTI
report, which was submitted before the meeting.
13. Logo
a.T. Gurley suggested that we contact logoworks for a
possible logo option.
i. Moved by W. Hayes, and Seconded by G. Best,
Approved Unanimously
14. Strategic Planning:
i. E. Wandel suggested that we hire a professional facilitator who can help us direct the meeting.
1. What do we offer to our Society members?
2. Computer Society offers courses
a. This is something that we could d o to serve our
membership and attract people.
3. What do we offer to our membership?
a. Transaction, newsletter and what?
b. The perception is that we are the RF society.
c. Some applications papers in the Transactions or
Newsletter would help greatly. We could consider paying an author.

Technical meeting oc St.Peterskurg Chanter (Russia)
Dmitry Tkachenko
O n November 17 a technical meeting
of St.Petersburg BT/CE/COM Chapter
was held at the MART Company in
St.Petersburg. About 20 participants
attended the meeting, both Chapter
m e m b e r s a n d r e p r e s e n t a t i v e s of
St.Petersburg industry, universities and
broadcasters. These Chapter meetings
at the MART company are held o n
regular basis d u e to support of the
MART c o m p a n y m a n a g e m e n t a n d
especially due to enthusiastic support
of Alexander Artamonov, D e p u t y
Director of MART Company, w h o usually makes a lot of efforts in organizing these meetings.
T h e General Director of MART
Company Saveliy Zhitomirsky opened
the meeting. He welcomed the participants and highlighted the importance
of digital technologies usage in new
developments especially in the field of
digital TV and Radio Broadcasting.
Alexander Artamonov, D e p u t y
Director of MART Company, described
general outlines of current activities of
Russian industry in the field of Digital
TV and Radio Broadcasting taking into
account the adoption of DVB-T standard in Russia. He also paid special
attention to DRM standard, which is
used for Digital Radio Broadcasting.
Professor Konstantin Glasman, the
Head of Department at St.Petersburg TV
and Cinema University, delivered a
detailed survey of 2 recent conferences
that he visited in September 2004. The
first conference was ISCE2004 that is a
traditional conference of IEEE Consumer
Electronics Society. In 2004 this conference was held in Reading, UK. Professor
Glasman has made preliminary arrangements to hold ISCE2006 conference in
St.Petersburg, and h e is currently working on organizing this conference.
Another conference described by
Professor Glasman was IBC2004 conference, which is traditionally held in
Amsterdam together with the trade
show. He mentioned 2 technical discussions that attracted his attention at
IBC. The first one was the discussion

o n E u r o p e a n w a y o n transition t o
HDTV. According to report of Profess o r G l a s m a n , EBU Project G r o u p
B/TQE (Television Quality Evolution)
proposes that Europe should use the
standard with 720 lines and progressive scan as an intermediate step in
the way t o higher resolution HDTV
(i.e., 1080 lines with progressive scan)
w h i l e a c o n s i d e r a b l e n u m b e r of
broadcasters and manufacturers
deploying HDTV now in other countries normally prefer HDTV with 1080
lines and interlaced scan. The standard with 1080 lines is compatible
with current cinema production and
there is sufficient choice of available
equipment for this standard.
The advantage of progressive scan
is better delivery of quick motion pictures (like sports) and it is also more
comfortable for those consumers who
already get used to quality of computer displays with progressive scan. On
t h e o t h e r h a n d , w i d e a d o p t i o n of
HDTV standard with 720 lines a n d
p r o g r e s s i v e s c a n in E u r o p e may
require more expensive equipment
b e c a u s e it may b e different from
equipment that is used in other countries. That is why it is possible that
EBU may p r o p o s e s o m e kind of a
trade-off solution.
O n e m o r e interesting issue discussed at IBC was introduction of
DVB-H standard, which is intended
for delivery of TV programs to handheld devices such as mobile phones,
personal devices, etc. DVB-H system
is b a s e d o n DVB-T system a s t h e
physical layer. DVB-H receivers are
active only approximately during 10
percents of time when they acquire
the information from the broadcast
stream. It allows prolonging the service time for batteries of handheld
devices. Another option of DVB-H
standard is improved performance in
high noise conditions that may take
place in many usage scenarios for
mobile devices.
Some companies like Nokia already
demonstrated DVB-H devices at IBC.
Spring 2005
St.Petersburg telecormnunication operators are interested to consider future
opportunities for introduction of DVB-H
services and MART Company is going
to produce D m - H modulators in 2005.
Nevertheless the weak point of D m - H
is that it is not quite clear if consumers
will be interested in this kind of service
and are willing to pay for such service.
Konstantin Kraskovskiy, the Chief
Designer of Consumer Electronics
Devices at Kozitskiy Plant s p o k e
about new developments of his company in the field of TV sets and set
top boxes capable to receive Digital
TV programs. Kozitskiy Plant was one
of major manufacturers of TV sets in
the former Soviet Union with manufacturing of millions units per year.
N o w , t h e c o m p a n y o u t p u t is
decreased d u e to competition from
foreign manufacturers that sell their
TV sets in the Russian market. Due to
introduction of Digital TV broadcasting in Russia, Kozitskiy Plant developed new types of hybrid consumer
devices that can receive both digital
a n d analog TV p r o g r a m s . Current
n ~ o d e l s u s e h a r d w a r e MPEG-2
d e c o d e r s , b u t f u t u r e m o d e l s will
include d o w n l o a d a b l e softmrare
decoders (e.g., MPEG-41, downloadable operating systems (e.g., based on
Linux) and downloadable user menus.
T h e d o w n l o a d of s o f t w a r e from
broadcast stream will allow upgrading
the consumer devices by the broadcaster or by the cable operator.
Finally, Dmitry T k a c h e n k o , t h e
Chapter Chair recalled to participants
that IEEE 2005 Renewal Campaign is
in progress now and asked all members to renew their memberships in
time. He also asked the participants to
consider submission of papers to the
IEEE Transactions of Broadcasting. It
is still a problem for Russian authors,

cannot write well in English, but we

PSIIP Requirements and
'Jaw r - ' r J '*- h
p'elp
By Jerry Whitaker, VP of Standards Development,
Advanced Television Systems Committee, Inc.
Now that the Federal Communications
Commission (FCC) has incorporated
ATSC Standard A/65B, "Program and
System Information P r o t o c o l for
Broadcast and Cable," into its rules,
stations have made great strides in
c o m p l y i n g with t h e provisions of
A/65R. This is good for broadcasters
and good for consumers.
Since the first version of the PSIP
Standard was published in 1997, compliance reflected good engineering
practice on the part of television stations, since the Standard offers benefits for both viewers and broadcasters.
PSIP is-in
fact-critical
t o proper
operation of the DTV system.
For the viewer, PSIP permits suitably
equipped receivers to build a n onscreen grid of channels and program
information for all DTV services. In
addition, the viewer can seamlessly surf
from NTSC t o HDTV t o SDTV. For
broadcasters, PSIP maintains local brand
identification through the "major channel number." PSIP identifies both the
DTV channel and the associated NTSC
channel and enables DTV receivers to
associate the two. In addition, PSIP tells
the receiver whether multiple program
channels are being broadcast and, if so,
how to find them. Furthermore, it identifies whether the programs are closed
captioned and conveys available v-chip
information, among other things.
The FCC mandatory PSIP requirements include the following:
Master Guide Table, which must
h a v e valid l i n k a g e s t o o t h e r
appropriate tables.
System Time Table, which must
contain time accurate to within
o n e s e c o n d w h e n s e n t (each
second).
Virtual Channel Table, which
must at least contain the NTSC
channel number for each 'major'
channel entry, a n d which the
FCC said they expect to contain
a c c u r a t e TSID, s e r v i c e t y p e ,
modulation m o d e , source ID,
and Service Location Descriptor.
At least the first four Event Information Tables (EIT), which must
contain t h e C a p t i o n Service
Descriptor ( w h e n DTV closed
captions are present), and the
Content Advisory Descriptor
( w h e n I ~ r o a d c a s t e r sp r o v i d e
such advisories). Note that the
FCC stated they expect broadcasters to send correct program
titles to inform consumers about
which programs are planned to
be broadcast.
Enter PMCP
The Programming Metadata Communication Protocol (PMCP) is a newly
published ATSC Standard that promise s to greatly simply the process of
generating highly-accurate PSIP data.
A/76 was developed by the ATSC Specialist Group o n Metadata Communications, T3/S1, under the leadership of
Graham Jones of NAB.
Because PSIP and other DTV metadata is originated or processed by several s e p a r a t e systems a n d related
equipment, u p to now there have been
difficulties in communicating the appropriate metadata to the PSIP generator.
Implementing PMCP will help ensure
that the transmitted PSIP information is
complete and correct, with minimum
manual intervention by the broadcaster.
PMCP is based primarily o n XML
(extensible m a r k u p language). It

Chair - Professor Alexander Mikerov at

enables broadcasters and manufacturers
to more easily interconnect systems that
process PSIP and other DTV metadata.
This includes, but is not limited to:
Traffic
Program management
Listing service
Automation
MPEG encoder
PSIP generator
PMCP is also extensible for other
types of metadata, and can convey
private information within the current
data structure.
With the XML schema being both
human and machine readable, PMCP
implementation becomes a more simplified process by specifying exactly
which elements are allowed in messages, their relationships, individual
attributes, and data types.
PMCP references and is complementary to existing ATSC Standards. It
supports the IS0 Standard V-ISAN for
unique identification of program content and carries all the information
needed in o n e message structure for:
Virtual channels
PSIP events
Programs
System Time Table
Regional Ratings Table
Private Information

IEEE BTS Adcam Meeting wirnubes Siidebar
encroach.
n) To grow membership, expand to baseband
O) Perception of BTS
p) BTS is the RF Society.
q) IEEE is too R&D oriented.
r) Broadcasters need more practical material.
Overview of BTS Strategic Planning and Membership Development Activities as presented to the BTS AdCom on 13
October, 2004 and to the TAB Society Review Committee o n
17 November, 2004.
1) BTS Strategy
BTS is pursuing a two-fold strategy to maintain its relevance in the face of a sea change in the broadcasting
industry:
a)"Fully
e m b r a c e " o u r field of
interest
Three years ago, we re-examined our official fieldof-interest statement with respect to the content in
our publications and symposium. \We realized that
the FOI is sufficiently broad to encompass the entire
chain from content creation to delivery, but that we
had not been fully embracing that broad field in our
content and activities, having fallen into a narrower
rut.
b) Affirm that "broadcasting" means "point-to-multipoint" The number o n e problem with using the
word "broadcasting" in any description of what our
society does is the question of what broadcasting
means. Once upon a time, the answer was easy - it
meant over-the-air radio and television. To many, it
still does - and that is part of our image problem.
In order to attract more content and membership
from the cable, satellite, and Internet communities, it
is important t o emphasize that w e are concerned
with all of these forms of point-to-multipoint communication.
2)
Strategic Planning
The BTS AdCom devoted considerable time to strategic
planning discussion at both the October 2003 and January 2004 meetings. At the October meeting, we began to
focus o n how to embrace more of our field of interest:
a) Broaden AdCom
b) Represent whole field of interest
c) Broaden international representation
d) Broaden membership
e) Engineers with a broader experience base & non-traditional broadcasters
d) Explore boundaries
e) Other organizations; e.g., SBE
h) Other IEEE societies
In January, discussion covered the following points:
i) Membership Base & Area of Interest
j) Employment in broadcast engineering is declining.
k) Over-the-air (OTA) broadcasting is a mature business.
1) Point-to-multipoint distribution of content includes
OTA, cable, satellite, and Internet.
m)Beyond our traditional OTA turf, other organizations
Spring 2005
3)
Possible response
a) Stretch our boundaries.
b) Consider an outside facilitator to help guide strategic
planning discussion.
C) Membership Development
d) Membership in BTS peaked at nearly 3400 in the
mid 1990s. This may have been due, in part, to the
intense interest in digital television development at
that time. Since then, BTS membership has steadily
declined, dropping below 2000 this year. We have
undertaken several activities to assess why members
are leaving and to recruit new members:
e) Booths at Industry Conferences: NAB, IBC, BroadcastAsia, CSTB
fl Member survey (IEEE All-Society Research Project 2003)
g) Past-member survey - 2004
h) Prospective member sunley - NAB 2004
i) More research needed, especially internationally
4)
What We've Learned
a) Better opportunities needed in education, networking, and local chapter activities
b) Most lost members n o longer employed in broadcasting
C) Cost of membership too high
d) Content too technical, academic, and irrelevant to
everyday work
5) What We're Doing
a) Revamp, Expand Newsletter to include:
b) Tutorials
C) Practical, applications-oriented articles
d) Worldwide reports
e) Expand Symposium
0 Tutorials o n non-traditional topics; e.g., IP multicasting, wireless broadband
g) Evening Workshop at 2004 Symposium
h) Increase support of chapter development and activities
i) Enhance virtual community
j) Offer more tutorials - NAB, IBC, CSTB
k) Foster affiliate relationships with AFCCE, SBE, SCTE,
and IBC partners
1) Raise profile of BTS in other societies a n d organizations
m)Continue assessment of member needs
IEEE Broadcast Technology Society Newsletter
6) International Broadcasting Convention
The IBC is of key strategic importance to BTS, so discussion of strategic planning would be incomplete
without consideration of its role. Held each September
at RAI in Amsterdam, IBC bills itself as "The World of
Content Creation, Management, Delivery."
a) Key statistics:
i) > 40, 000 attendees / 120 countries (up 12%
from 2003)
ii) 36, 000 sq. ft. exhibition / 1,000 stands
iii) 5-day technical conference
iv) BTS has 11% ownership stake, worth over
$300K a year
b) IBC Partners
The IBC is owned "by the industry for the industry."
The six partners are all not-for-profit industry organizations. The profits from IBC are returned to the
partners for the benefit of their members and the
industry at large. The partners are:
i) IEEE-BTS
ii) IEE (Institution of Electrical Engineers)
iii) IABM (International Association of Broadcasting
Manufacturers)
iv) RTS (Royal Television Society)
SCTE (Society of Cable Telecommunication
V)
Engineers, UK organization unaffiliated with US
EEE Brordcat Tochndogy Society Nodottor
organization of the same name)
vi) SMPTE (Society of Motion Picture and Television
Engineers)
c) BTS has identified each of our IBC partners as an
affiliate organization for membership purposes, and
we are attempting to establish cross-promotion
opportunities and joint activities.
d) IBC Involvement
BTS is actively involved with IBC at several levels:
i) Partnership Board
ii) IBC Council - Broadly based advisory group
iii) "Partnership Village" membership stand
iv) Joint Tutorial with SMPTE at IBC2004
V) Evening Reception with SMPTE at IBC2004
e) IBC 2004
Various speakers from around the world assessed the
state of the industry and its direction from their perspective. They covered the three aspects of broadcasting:
(1) Creation
(2) Management (or Aggregation)
(3) Delivery (or Distribution)
0 The BTS AdCom, in upcoming strategic planning, will
consider the suggestions about the future of broadcasting provided by directional groups at the IBC.
